I personally do not use bidbots except for a couple of experiments I tried in the past. I do feel they have a place in the ecosystem for two reasons: (1) a better way to promote initiatives and posts that need attention and (2) a place where passive investors could feel they are getting an ROI for they stake. While both can be abused, I think that is why there are a number of high profile accounts out there to deter abused with blacklists or just by calling out actions of the users. However, looking at the data you provide, I think the balance has shifted somewhat towards a better spot were value can be created from all participants. I think only time will tell.
